Embodiments of this disclosure relate generally to solar power.
Today, installing and removing solar modules in a solar farm experience many problems including a need to pause work at night, crews need to be trained because no uniform solar tracker and solar module exists as well as the workers in the crew can change; and thus, training may need occur for each solar farm installation, a repetitive task performed over and over again can lead to human complacence and errors over time, and weather and bad conditions interfere with the work.
Provided herein are various methods, apparatuses, and systems for an intelligent robotic system and task orientated processes. In an embodiment, an autonomous solar module installation platform can be used for solar module installation onto a solar tracker. The autonomous solar module installation platform can include an off-road capable base vehicle and a robotic arm, mounted on the off-road capable base vehicle, for the solar module installation onto the solar tracker.
The off-road capable base vehicle and the robotic arm can communicate with each other and cooperate their movements to proceed to the solar tracker and align with the solar tracker in order for the robotic arm to pick up and lift the solar module during an installation of the solar module onto the solar tracker.
These and many more embodiments are discussed.
While the design is subject to various modifications, equivalents, and alternative forms, specific embodiments thereof have been shown by way of example in the drawings and will now be described in detail. It should be understood that the design is not limited to the particular embodiments disclosed, but—on the contrary—the intention is to cover all modifications, equivalents, and alternative forms using the specific embodiments.
In the following description, numerous specific details can be set forth, such as examples of specific data signals, named components, number of frames, etc., in order to provide a thorough understanding of the present design. It will be apparent, however, to one of ordinary skill in the art that the present design can be practiced without these specific details. In other instances, well known components or methods have not been described in detail but rather in a block diagram in order to avoid unnecessarily obscuring the present design. Further, specific numeric references such as the first server, can be made. However, the specific numeric reference should not be interpreted as a literal sequential order but rather interpreted that the first motor is different than a second motor. Thus, the specific details set forth can be merely exemplary. The specific details can be varied from and still be contemplated to be within the spirit and scope of the present design. The term “coupled” is defined as meaning connected either directly to the component or indirectly to the component through another component.
1. An off-road, off-road capable base vehicle 100 with a robotic arm 120 for solar module placement;
2. A robotic cell having a robotic arm 120 and optionally a track for solar module placement;
3. One or more software coded methods used to install solar modules;
4. A set of cooperating solar module carrier-robots 200, 209 to carry one or more pallets of solar modules; and
5. Optionally, a cooperating fastening robot 350 to fasten one or more solar modules onto a solar tracker.
The off-road capable base vehicle, such as an autonomous ground vehicle, and the robotic arm are constructed to communicate with each other and to cooperate their movements to proceed to the solar tracker and align with the solar tracker. The robotic arm then can pick up and lift the solar module during an installation of the solar module onto the solar tracker.
The autonomous solar module installation platform can be configured to be autonomous for the entirety of moving along a row of trackers using at least a global positioning system (GPS) to each individual solar tracker and lifting the solar modules/panels, at least, into installation position using a vision system onto the corresponding mating mounts on the solar tracker. The off-road capable off-road capable base vehicle platform 100 serves as a base. The off-road capable base vehicle platform 100 has code and sensors to be autonomous for the entire process of moving along a row of solar trackers and installing solar modules/panels onto each solar tracker achieving autonomous operation on its own. The off-road capable base vehicle 100 is coded to perform every step of the installation process of the solar modules/panels onto the tracker, itself achieving more autonomous operation. Alternatively, the off-road capable base vehicle 100 can hold and hover the solar module above the position where the solar module needs to integrate onto the tracker, and allow a human to guide the solar module into the mounting components on the solar tracker for a final step the installation process. A robotic arm 120 can support the weight of the solar module during the installation with the human guiding the solar module onto the solar tracker in its mounting components. The off-road capable base vehicle 100 will work in tandem with the human installer to pick up and install solar modules onto the solar tracker and then have the human operator fasten and secure the solar modules in place. The robotic arm 120 can go into an install mode when hovering the solar module above the position where the solar module needs to integrate onto the tracker. In install mode, the robotic arm is coded to hold the solar modules weight and also mimic a human's lead to move the solar module, such as advancing forward and/or rotating an axis of the solar module. The human can cooperate with the off-road capable base vehicle 100 to secure and fasten the solar panel when properly positioned in place onto the solar tracker. The off-road capable base vehicle 100 also can have the additional capability to incorporate human operated remote control operations into its own operations of driving and robotic arm 120 operation. In some situations, it might be easier for a human to assist in the driving and robotic arm 120 operation.
The off-road capable base vehicle 100 will generally drive the off-road capable base vehicle 100 itself to each solar tracker and align itself with that solar tracker automatically in order to place the solar modules onto that solar tracker. The off-road capable base vehicle 100 can self-drive itself using a vision system, such as a camera based-computer vision system and/or Lidar, sensors, and optionally a remote for assisting in various aspects such as driving. The off-road capable base vehicle 100 has a self-driving system using self-driving software and sensors, such as the vision system (camera based vision system, Lidar vision system, etc.) and other sensors, and a remote for assisting in various aspects, such as driving and a robotic arm to perform pick up and place operations. The off-road capable base vehicle can have driving software and cooperating computing hardware to autonomously drive itself to the solar tracker and then align itself with the solar tracker.
By the very nature of solar farms, each row of solar trackers is located on a relatively known location on a map of the solar farm. Each solar farm has one or more devices that give off precise GPS coordinates. Normally, at least one GPS device is located in a control room of a solar farm. Each solar tracker is usually installed in a pre-planned location on that farm per its planning drawings; and thus, the off-road capable base vehicle 100 can drive directly to the beginning of each row by using the approximate GPS coordinates of that row of trackers and/or the off-road capable base vehicle 100 can calculate a distance to a row of solar trackers from a known GPS coordinates and then drive a specific distance and direction from a device on the solar farm that can broadcast or otherwise convey its GPS coordinates in order to eventually arrive at a target solar tracker. In either circumstance, the off-road capable base vehicle 100 will roughly align itself with each row of solar trackers and then proceed down the row to align itself with each individual solar tracker when installing solar modules onto those trackers via GPS based decisions. The GPS based decisions can be the GPS coordinates directly on the solar tracker and/or calculations of distance and direction from known GPS coordinates. Note, the off-road capable base vehicle 100 has its own GPS device that it can reference and a memory, processing unit, and software to reference a plot/map of that solar farm. Next, the ground vehicle is coded to use its computer vision and/or Lidar system for fine adjustments to account for any imperfection on how planar/straight the real row of solar trackers is and/or an exact location in the solar farm of each individual solar trackers is and the ground vehicle's positioning relative to the solar tracker for the solar module installation and/or removal. The off-road capable base vehicle 100 can also have a manual steering wheel, accelerometer, and braking system in order for a human to assist in moving the vehicle. Thus, the off-road capable base vehicle 100 system uses computer vision and GPS coordinates to be able to self-drive around a solar farm, including up and down rows of solar trackers, as well as to autonomously move to individual solar trackers during a solar module installation and/or replacement session.
Next, the off-road capable base vehicle 100 with its robotic arm 120 can self-level at least the robotic arm 120 relative to the solar tracker, accounting for a terrain, using a leveling mechanism consisting of any of i) screw actuators, ii) hydraulic cylinders, iii) airbags, iv) pneumatic actuators, and v) any combination of these, at multiple corners of a deck of the off-road capable base vehicle 100 to level the robotic arm 120 on the deck relative to the solar tracker. The leveling mechanism cooperates with the level sensor in order to level relative to the solar tracker. In an embodiment, each corner of the deck of the off-road capable base vehicle 100 can have self-level actuators such as screw mechanisms, airbags, and/or hydraulic actuators, to level the robotic arm 120 with respect to an individual solar tracker. The self-leveling actuators cooperate with a tilt sensor and/or incline sensor/meter in order to level the robotic arm 120 so calculations for arm positioning algorithms to install and/or uninstall a solar module on that type of solar tracker are correct, relative to the particular solar tracker next to it. The self-level actuators will self-level the deck and robotic arm 120 on the deck relative to the tracker and the terrain so that the off-road capable base vehicle 100 can adapt to any job site conditions; and thus, any deviations particular to the current solar tracker undergoing a solar module installation compared to another solar tracker in a given solar farm.
Next, both the robotic cell containing the robotic arm 120 and the off-road capable base vehicle 100 are designed and constructed to be used off-road and outdoors for installation work on a job site.
The autonomous solar module installation platform for solar module installation onto a solar tracker is built for off-road (e.g. muddy terrain, sandy terrain, etc.) operation. The off-road autonomous solar module installation platform serves as a mobile base to autonomously move to individual solar trackers in a solar module installation.
Again, the off-road capable base vehicle 100 is coded to autonomously drive itself to the solar tracker and align itself with the solar tracker in order to place one or more solar modules onto the solar tracker. The off-road capable base vehicle 100 has an ability to autonomously drive itself via use of a computer vision system and/or a Lidar system cooperating with a GPS sensor and driving software resident in a drive module for the off-road capable base vehicle 100 to drive itself to the solar tracker and align itself with the solar tracker. The driving software is coded to any of 1) drive a route to GPS coordinates of the solar tracker when the solar tracker has a GPS device on that solar tracker and/or when GPS coordinates (e.g. GPS service) is available at a particular solar tracker location and 2) calculate one or more specific distances, directions, and routes from known GPS coordinates on a solar farm to the solar tracker and then drive those distances, directions, and routes to the solar tracker (when GPS service is not possible at the particular solar tracker's location).
Again, the robotic arm 120 is configured to work with the sensors and coded algorithms to pick up and place the solar modules from the deck/container of the solar module carrier-robot 200 into position to be connected into the solar tracker. This robotic arm 120 can travel up and down, e.g., a 6-axis or a 7-axis robotic arm 120 track to be able to pick up and place solar modules in place while the off-road capable base vehicle 100 remains in place. The off-road capable base vehicle 100 can self-level the platform relative to the tracker and the terrain via its mechanisms discussed herein. The robotic arm 120 can pick up the solar module from the deck/container of the solar module carrier-robot 200 coupled to either the front or the rear of the autonomous solar module installation platform for solar module installation. The robotic arm 120 can raise the solar module out and over to the solar tracker, and then place the solar module very near the panel mounting location on the solar tracker via using the GPS coordinates of the tracker, its computer vision system, and a Lidar-based system for placing the solar modules into the corresponding panel mounting location on the tracker. The robotic arm 120 lifts the solar modules/panels into installation position to hover over the tracker mounts. The robotic arm 120 can hold and suspend the weight of the solar module and then mechanically follow i) a human's pulling or pushing of the solar module or ii) similar controls from a remote control in order to then guide the solar module, while the robotic arm 120 holds the weight of the solar module, into the panel mounts on the solar tracker. In an embodiment, when the robotic arm 120 has the solar module approximate to the panel mounts to the solar tracker, then a person can use a remote control to lower and place the solar module into the mounts of the tracker or in some cases guide the panel with his or her hands into the mounts of the tracker. In an embodiment, the robotic arm is configured to pick up the solar module from a deck, raise the solar module out and over to the solar tracker, and then, at least, hold the solar module in place to install the solar module onto the solar tracker via using both i) a GPS coordinates of the solar tracker and ii) a visual Lidar-based system.
A construction and shape of a body of robotic arm 120 is configured to have a range of motion of, at least, 360 degrees. A robotic installation cell is constructed with materials and powerful enough motor to have a robot arm capable of readily handling a solar module weighing 60-200 pounds (lbs.) in low to moderate windy conditions. In an embodiment, the robot arm is constructed to readily handle a solar module weighing 60-80 pounds. In addition, a chassis of the vehicle 100 is made heavy enough with a low center of gravity to counter balance the robotic arm holding a 200 pound solar module in heavy winds. The robotic installation cell has a multi-axis track to move the robot arm in, for example, 7 axes independently of the platform moving. The robotic installation cell is configured to cooperate with the GPS and computer vision system to control and determine solar module placement. In an embodiment, the robotic arm can pick up the solar panel from a deck, raise the solar module out and over to the solar tracker, and then place the solar module in place onto the solar tractor via using both the GPS coordinates of the solar tracker and a visual LIDAR-based system for placing the solar panels into the corresponding location onto the solar tracker. The off-road capable base vehicle is configured to put multiple solar modules in place, installed, and secured per each time that the off-road capable base vehicle 100 moves itself and then self-levels in place. The robotic arm can travel forward and backward in the track to place the multiple solar panels in place while the vehicle does not have to move and has self-leveled itself.
In an embodiment, the robotic cell with the robotic arm is configured to ensure at least two pallets of solar modules, one in use and one in queue are approximate for continuous operations. The robotic cell uses weight sensors, and determines when a new pallet is needed and makes a call and sets off visual signal. The robotic cell has an industrial robotic arm on a robotic 7th axis track to index installation independently from the platform. This allows the robot to install several modules one after another before running out of track. Once the robot runs out of track to index, the entire platform will move forward and reset the index and recalibrate. The robot arm determines placement using GPS and a vision component. The robotic arm can be guided by a vision system which includes one or more of i) a computer vision system, ii) a Lidar system, and iii) any combination of both, to use suction cups or other grasping mechanism to lift the solar module off of a deck of one of i) the off-road capable base vehicle and ii) a solar module carrier-robot distinct from the off-road capable base vehicle. The robot then uses suction cups or other mechanism to pick, place, and hold. The computer vision can use a set of suction cups such as 2 rows of 3 suction cups each. A tool is added onto the robotic arm with quick coupler. An actuator creates a vacuum, for the rows of suction cups where each cup has its own vacuum. An air nozzle cooperates with the set of suction cups on the robotic arm to blow off, any of, dust, sand, and other debris on a surface of the solar module and then the robotic arm acts to compress the suction cups to create a vacuum attachment to the surface of the solar module. Note, a normal procedure can be for a human to wipe of a surface of a solar module on top of the stack of modules before sending the robot out to meet up with the off road capable vehicle 100. The solar modules may sit vertically on their edge on the deck to further assist in keeping debris off the surface of the solar module.
The amount of vacuum can be sensed to monitor whether the solar module is positively engaged to pick up the solar panel and then positively disengaged to drop the solar module in place. When the robotic arm moves toward the surface of the solar module, then a depth sensor (e.g. spring loaded) can be used to measure a suction cup's engagement to the face of the solar panel when lifting the solar panel off of the deck of the solar module carrier-robot 200 onto the horizontal supports of the solar tracker.
Simultaneously, the robotic cell communicates with the fastener robot and/or cooperating human and waits for an “all fastened” signal to be returned indicating the installation processes is complete for that solar module.
The off-road capable base vehicle 100 can have a wind sensor and an algorithm to compensate for the wind and the direction the wind is blowing when installing the solar panels. The wind sensor can be mounted on an extendable pole to go high up on a chassis to determine both velocity and direction of the wind. The algorithm is configured to offset/compensate for the velocity and direction the wind is blowing when installing the solar module onto the solar tracker. The algorithm can be configured to temporally stop working when go over a maximum wind speed. The off-road capable base vehicle may also have a moveable wind block wall that raises from the deck to block the wind when in windy conditions that would substantially affect the robotic arm picking up and placing the solar panel onto the tracker.
The robotic arm 120 may be completely guided by computer vision to use suction cups or other grasping mechanism to lift the solar module out of the container of the solar module carrier-robot 200 to be near the horizontal supports of the tracker. Note, a human can have remote control for manual override on the robotic arm 120 to affect the angle and movement of the robotic arm 120 to assist in the picking up and placement of the solar module on to the tracker.
The off-road capable base vehicle 100 can put one or more solar modules in place per each time that the vehicle itself moves and then self-levels in place. Note, the off-road capable base vehicle 100 may have a library of known types of solar trackers and procedures of how one or more solar modules should be installed onto a particular type of solar tracker targeted for installation, where at least one of i) the automated ground vehicle and ii) the robotic arm is configured with an intelligence module to select and follow a procedure for that particular type of solar tracker to install the solar module properly in place, guided by at least a vision system to install the solar module in place. In addition, the library contains solar module dimensions and weight of individual solar modules on a per manufacturer and panel type basis.
The off-road capable base vehicle 100 will then select and follow the procedure for that particular type of solar tracker to install the solar module properly in place, guided by the computer vision and GPS, and then secure the solar module in place. The panel sizes can vary per manufacturer and the tracker's height and mountings can also differ per manufacturer. The off-road capable base vehicle 100 uses its vision system to locate and make decisions, for example, on placement of solar modules, allowing adaptation to any tracker or mounting system by referencing the library of known solar trackers and the installation steps for each solar tracker.
The deck of the off-road capable base vehicle 100 can have a robotic installation cell for pick up and placement of solar modules/panels. The robotic arm is configured to be capable of moving in multiple axes of rotation. The robotic arm can be in a multiple axes of rotation track. The robot arm 120 is constructed to be able to pick up and place the solar module for installation on the solar tracker using the multi-axes during picking up and placing the solar module, independently of the base vehicle 100 moving. The robotic installation cell can use GPS and a Vision system to control and determine solar module placement. The off-road capable base vehicle platform 100 can have a section on its deck where it's a robotic arm track and robotic arm are located. The robotic arm is configured to work with the sensors and coded algorithms to pick up and place the solar panels onto the solar tracker. This robotic arm can travel up and down the multiple-axis robotic arm track to be able to pick up and place solar panels in place while the off-road capable base vehicle remains in place. Note, the Vision system and for example its multiple stereo cameras and/or 3D camera, and/or laser based Lidar, system can be mounted on extendable moveable poles or platforms so that the solar module does not block the vision system during the solar module pick up and installation process.
In an embodiment, the off-road capable base vehicle 100 is able to navigate outdoors in off-road construction environments using any of i) a combination of computer vision and LIDAR system, ii) locally remote controlled, iii) by teleoperation (remote operator), and/or iv) by a pre-planned (recorded) route with calculable distances and directions from a known GPS coordinates. The off-road capable base vehicle 100 can install panels on multiple different types of trackers, work on flat terrain, work on unleveled terrain, and many other functions. The off-road capable base vehicle 100 can have one or more of i) off-road deep-tread tires (e.g. off-road agricultural type tires/tractor tires), ii) a tracked belt drive system, and iii) a powerful enough engine to be able to maneuver in tough terrain. The off-road capable base vehicle 100 engine has enough horsepower to drive the several thousand pounds of the ground vehicle with a fully loaded payload capacity of solar modules (potentially on a side vehicle) such as 8,000 lbs. or greater. Next, the off-road capable base vehicle 100 may be battery-operated and/or have a gas-powered engine. The track drive system and/or off terrain deep tread mud tires can be powered through a direct drive system via the electric motor. Each track can be operated independently, so that the off-road capable base vehicle 100 can turn in place easily. Each track being able to move independently of the other track also allows the vehicle to get unstuck easier and be more reliable in off road conditions. The off-road capable base vehicle 100 system is able to move in rough terrain, sandy conditions, and muddy conditions with the heavy weight of the vehicle and its fully loaded stack of solar modules. When the off-road capable base vehicle 100 is designed to cooperate with the solar module carrier-robots, then each different movable vehicle can have a smaller/less powerful engine.
This autonomous solar module installation platform is a truly agnostic installation robot that installs panels on any solar tracker (tracker manufacturer and type agnostic) and on any grade or terrain (terrain agnostic).
Most importantly, a fleet of two or more vehicles, including the off-road capable base vehicle 100, can each have a wireless communication system to exchange communications with the off-road capable base vehicle 100, currently installing solar modules, to perform the solar module installation. A control room in the solar farm, through its own communications module can wirelessly coordinate activities of bringing additional solar modules over to the off-road capable base vehicle 100 currently installing solar modules, when an amount of solar modules remaining is at or below a threshold amount, so that the robotic arm and the off-road capable base vehicle 100 can perform the solar module installation on a continuous basis. The off-road capable base vehicle 100 can be configured to wireless communicate and otherwise cooperate with one or more additional vehicles directly and/or through the control room. The additional vehicles can be another off-road capable base vehicle 100 when this vehicle is constructed to both carry the solar modules and have the robotic arm. (See e.g.
The off-road capable base vehicle 100 can have, for example, a coupling mechanism that mechanically and electrically connects a solar module carrier-robot 200 and the off-road capable base vehicle 100 for solar module installation. The coupling mechanism also has an electronic release to decouple the solar module carrier-robot 200 and the off-road capable base vehicle 100.
Each solar module carrier-robot 200 has a deck with space for one or more pallets of solar modules on its deck. A solar module carrier-robot 200 can have, for example, a slanted deck section for placing stacks and pallets of solar module modules onto its deck.
Alternatively, (see
The deck of the off-road capable base vehicle 100 and/or its cooperating solar module carrier-robot 200 can have an area for placement of two or more pallets of solar modules/panels onto the deck, with sensors in that area to determine by any combination of i) by weight, ii) by vision, and/or iii) by count, to determine when an amount of remaining solar modules/panels on the deck is getting low and/or is empty. The solar module carrier-robot 200 may have sensors to measure the weight of the pallets of solar modules on the deck of the solar module carrier-robot 200 to sense when the amount of solar modules on the deck is running low and should send out an automated signal to a material handler to come over to the vehicle with more pallets of solar modules to be transferred onto the deck.
The coupling mechanism can mechanically and electrically connect the solar module carrier-robot 200 and the off-road capable base vehicle 100 via e.g. a mechanical hitch and an electrical mating interface. The coupling mechanism can be installed on both a front and a rear of the off-road capable base vehicle 100 for solar module placement. During a coupling operation, the off-road capable base vehicle 100 communicates and cooperates with the solar module carrier-robot 200 through the connecting mechanical. While moving/driving and coupled, the solar module carrier-robot 200 can communicate and place the drive system of the solar module carrier-robot 200 into a follower mode making the drive system of the off-road capable base vehicle 100 the master. The solar module carrier-robot 200 can have its own GPS and a vision system to help find the off-road capable base vehicle 100 as well as aid in coupling the coupling mechanism between the two. The systems (e.g. computer vision system, GPS, etc.) of the solar module carrier-robot 200 can communicate and cooperate with the off-road capable base vehicle 100 and/or the robotic arm 120 to assist when a solar module is being installed. The coupling mechanism also has a de-coupler tool to allow the solar module carrier-robot 200 to decouple and go get more solar modules.
Next, the off-road capable base vehicle 100 may have a battery along with the gas-powered engine or diesel powered engine. The chassis will contain the engine and other drive components for the tracks and/or wheels. The chassis can contain the DC drive motors for the robotic arm. The power system is configured to have one or more three-phase AC motors and DC drive motors. The power system also has power surge protection.
Both the solar module carrier-robot 200 and the autonomous solar module installation platform for solar module installation can share a similar chassis. The chassis can have a diesel generator for a power supply. The diesel generator needs to supply enough power to move the roughly 5000 pound robot and in the case of the solar module carrier-robot 200 an example 8000 pound load of solar modules being carried by the solar module carrier-robot 200. The chassis has a housing to contain the electronic systems (e.g. a communications module, intelligence module) within the chassis that is water proof and dust proof via i) an access cover to the housing and ii) cooling lines into and out of the housing. The chassis contains the computing system and other electronics in a housing within the chassis that is water and dust proof with access through a cover. The chassis has a cooling system for the electronic system communications module, intelligence module, etc. The construction and shape of the chassis is designed to keep portions of the chassis and other structures raising off a deck of the chassis to be low enough in height to allow the robotic arm to have a range of motion of, at least, 360 degrees. The electronic systems support the off-road capable base vehicle and the robotic arm communicating with each other. In addition, the chassis
In an embodiment, the off-road capable base vehicle 100 with the robotic arm 120 operates and coordinates with the fastening robot 350 that is configured to fasten the solar modules to the solar tracker. The fastening robot 350, which is configured to fasten the solar modules to the tracker, may fasten those solar modules by tightening up and installing bolts on threaded rods of the solar modules, by welding nuts in place, riveting, and/or other mechanisms for the solar modules to be secured to the solar tracker once properly placed into alignment on the solar tracker. The two robotic vehicles communicate with each other when 1) the automatic ground vehicle picks up and places the solar module into place onto the tracker then 2) a communication is sent to the fastening robot 350 to fasten the solar module that has been placed in place onto the horizontal supports of the tracker. The tracker has multiple horizontal supports and they have multiple bolt holes to accommodate different solar modules onto the tracker.
Alternatively, a human can fasten and secure the solar modules in place. Thus, the off-road capable base vehicle 100 may operate exactly as described; yet, a human may cooperate with the off-road capable base vehicle 100 to secure and fasten the solar module when properly positioned onto the tracker in place (vs a fastening robot 350). In addition, the human operator may have slightly greater control over the robotic arm 120 in the placement of the solar modules via the remote joystick.
The off-road capable base vehicle 100 can be physically large (20 ft×8 ft) to have deck space to accept two or more pallets of solar modules as well as room for a robot track for the robotic arm 120 to move along a portion of the deck.
In use, the off-road capable base vehicle 100 may be used to install solar modules onto a tracker in a new installation of solar modules in a solar farm. In addition, the off-road capable base vehicle 100 may be used to remove a damaged solar module and then install a new solar module in an existing solar farm. The removal operations in the software needs to reverse most of the steps in the installation steps. Accordingly, the off-road capable base vehicle 100 can use the GPS coordinates associated with a given tracker to go to that tracker and cooperate with the fastening robot 350 to unsecure a damaged solar module, pick up and remove the damaged solar module, pick up and install a new solar module onto the tracker, and then cooperate with the fastening robot 350 to secure the new panel in place on the tracker. The autonomous solar module installation platform can also be used to deconstruct the solar farms for retrofit of new panels.
Next, the off-road capable base vehicle 100 may also be equipped with a set of lights on various locations of the ground vehicle. The off-road capable base vehicle 100 has a set of lights to operate at night time as well as a low-light imaging sensor in a computer vision system to be able to operate in a low-light conditions and to continue the solar module installation onto solar trackers in a solar farm during both night and day. The computer vision may use night vision in order to pick up and place the solar modules in the proper positions and alignment at night. An advantage of the off-road capable base vehicle 100 is that the vehicle may install solar modules continuously throughout the day and night; thereby, cutting down the overall amount of time/number of days that is needed to install solar modules onto the rows upon rows of trackers in a solar farm. The robotics will reduce labor costs, have better productivity, and increase safety. The off-road capable base vehicle 100 having autonomy allows installation away from regular hours, provides a more flexible schedule, provides better visibility via real-time tracking tools, and aids in the future of labor shortages.
The system uses at least a vision system and one or more robots to install the solar modules. The off-road capable base vehicle 100 does not require any pre-fab or double handling of modules. The off-road capable base vehicle 100 has a computer vision system to install the solar module and assist in driving, has a computing system with programmed intelligence to make decisions on solar module installation and driving, and a communication module to wirelessly communicate with other apparatus, such as the solar module carrier-robot 200.
A fleet of two or more solar module carrier-robots each can have a coupling to connect to the off-road capable base vehicle in order to perform the solar module installation. The fleet of robots can be coded to cooperate with each other, the off-road capable base vehicle, and a central control room to install panels on a solar farm. A central robotic operation management system through a communications module and software manages and identifies the location of all of the robots as well as coordinates their activities of bringing in more solar modules to the off-road capable base vehicle to install the solar modules. The off-road capable base vehicle 100 and/or solar module carrier-robot 200 may have sensors to take the weight of the pallets of solar modules on the deck of the off-road capable base vehicle 100 and/or solar module carrier-robot 200 to sense when the amount of solar modules on the deck is running low and should send out an automated signal to a material handler for a second solar module carrier-robot 200 to come over to the off-road capable base vehicle 100 with more pallets of solar modules. The central control room through a communications module and software coordinates activities of bringing additional solar modules on an example first solar module carrier-robot over to the off-road capable base vehicle and then an example second solar module carrier-robot so that the off-road capable base vehicle 100 and the robotic arm 120 can perform the solar module installation on a continuous basis. When the signal is sent that the first solar module carrier-robot is getting low on an amount of solar modules, then the second solar module carrier-robot loaded with a pallet of solar modules will be sent out to the coordinates of the off-road capable base vehicle 100. When the off-road capable base vehicle 100 is within short range wireless communication range of the second solar module carrier-robot loaded with a new pallet of solar modules, the two vehicles will communicate and cooperate to couple through the coupling mechanism. The first solar module carrier-robot when it is completely empty of solar modules is coded to engage a spring based disengagement component to decouple from the off-road capable base vehicle 100.
The robots (ground vehicle, panel carrier) will reduce human labor costs, have better productivity, and increase safety.
The communications network 820 can connect one or more server computing systems selected from at least a first server computing system 804A, two or more solar module carrier-robots 200, 209, an autonomous vehicle 100, and one or more client computing systems 802A thru 802F to communicate with each other. The vehicles on the solar farm, e.g. solar module carrier-robots 200, 209, the autonomous vehicle 100, another the autonomous vehicle 100 but lengthened to carry solar modules, all can wirelessly talk to each other as well as they communicate with the control room in a solar farm using these networks. The server computing systems 804A and 804B can each optionally include organized data structures such as databases 806A and 806B. Each of the one or more server computing systems 804A and 804B can have one or more virtual server computing systems, and multiple virtual server computing systems can be implemented by design. The network 820 can have one or more firewalls to protect data integrity.
The client computing systems can be selected from a first mobile computing device 802A (e.g., smartphone with an Android-based operating system), a second mobile computing device 802E (e.g., smartphone with an iOS-based operating system), a first wearable electronic device 802C (e.g., a smartwatch), a first portable computer 802B (e.g., laptop computer), a third mobile computing device or second portable computer 802F (e.g., tablet with an Android- or iOS-based operating system), the off-road capable base vehicle 100, solar module carrier-robots 200, 209 and the like. Each of the client computing systems (e.g., 802A, 802C, 802D, 802E, 802F, 802G, 802H, and/or 804C) can include, for example, the software application or the hardware-based system in which the training of the artificial intelligence can occur and/or can be deployed into. Each of the one or more client computing systems can have one or more firewalls to protect data integrity.
It should be appreciated that the use of the terms “client computing system” and “server computing system” is intended to indicate the system that generally initiates a communication and the system that generally responds to the communication. For example, a client computing system can generally initiate a communication and a server computing system generally responds to the communication. No hierarchy is implied unless explicitly stated. Both functions can be in a single communicating system or device, in which case, the client-server and server-client relationship can be viewed as peer-to-peer. Thus, if the first portable computer 802B (e.g., the client computing system) and the server computing system 804A can both initiate and respond to communications, their communications can be viewed as peer-to-peer. Additionally, the server computing systems 804A and 804B include circuitry and software enabling communication with each other across the network 820. Server 804B may send, for example, simulator data to server 804A.
Any one or more of the server computing systems can be a cloud provider. A cloud provider can install and operate application software in a cloud (e.g., the network 820 such as the Internet) and cloud users can access the application software from one or more of the client computing systems. Generally, cloud users that have a cloud-based site in the cloud cannot solely manage a cloud infrastructure or platform where the application software runs. Thus, the server computing systems and organized data structures thereof can be shared resources, where each cloud user is given a certain amount of dedicated use of the shared resources. Each cloud user's cloud-based site can be given a virtual amount of dedicated space and bandwidth in the cloud. Cloud applications can be different from other applications in their scalability, which can be achieved by cloning tasks onto multiple virtual machines at run-time to meet changing work demand. Load balancers distribute the work over the set of virtual machines. This process is transparent to the cloud user, who sees only a single access point.
Cloud-based remote access can be coded to utilize a protocol, such as Hypertext Transfer Protocol (“HTTP”), to engage in a request and response cycle with an application on a client computing system such as a web-browser application resident on the client computing system. The cloud-based remote access can be accessed by a smartphone, a desktop computer, a tablet, or any other client computing systems, anytime and/or anywhere. The cloud-based remote access is coded to engage in 1) the request and response cycle from all web browser-based applications, 3) the request and response cycle from a dedicated on-line server, 4) the request and response cycle directly between a native application resident on a client device and the cloud-based remote access to another client computing system, and 5) combinations of these.
In an embodiment, the server computing system 804A can include a server engine, a web page management component or direct application component, a content management component, and a database management component. The server engine can perform basic processing and operating-system level tasks. The web page management component can handle creation and display or routing of web pages or screens associated with receiving and providing digital content and digital advertisements, through a browser. Likewise, the direct application component may work with a client app resident on a user's device. Users (e.g., cloud users) can access one or more of the server computing systems by means of a Uniform Resource Locator (“URL”) associated therewith. The content management component can handle most of the functions in the embodiments described herein. The database management component can include storage and retrieval tasks with respect to the database, queries to the database, and storage of data.
In an embodiment, a server computing system can be configured to display information in a window, a web page, or the like. An application including any program modules, applications, services, processes, and other similar software executable when executed on, for example, the server computing system 804A, can cause the server computing system 804A to display windows and user interface screens in a portion of a display screen space.
Each application has a code scripted to perform the functions that the software component is coded to carry out such as presenting fields to take details of desired information. Algorithms, routines, and engines within, for example, the server computing system 804A can take the information from the presenting fields and put that information into an appropriate storage medium such as a database (e.g., database 806A). A comparison wizard can be scripted to refer to a database and make use of such data. The applications may be hosted on, for example, the server computing system 804A and served to the specific application or browser of, for example, the client computing system 802B. The applications then serve windows or pages that allow entry of details.
The system memory 930 includes computer storage media in the form of volatile and/or nonvolatile memory such as read-only memory (ROM) 931 and random access memory (RAM) 932. These computing machine-readable media can be any available media that can be accessed by computing system 900. By way of example, and not limitation, computing machine-readable media use includes storage of information, such as computer-readable instructions, data structures, other executable software, or other data. Computer-storage media includes, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disks (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other tangible medium which can be used to store the desired information and which can be accessed by the computing device 900. Transitory media such as wireless channels are not included in the machine-readable media. Communication media typically embody computer readable instructions, data structures, other executable software, or other transport mechanism and includes any information delivery media.
The system further includes a basic input/output system 933 (BIOS) containing the basic routines that help to transfer information between elements within the computing system 900, such as during start-up, is typically stored in ROM 931. RAM 932 typically contains data and/or software that are immediately accessible to and/or presently being operated on by the processing unit 920. By way of example, and not limitation, the RAM 932 can include a portion of the operating system 934, application programs 935, other executable software 936, and program data 937.
The computing system 900 can also include other removable/non-removable volatile/nonvolatile computer storage media. By way of example only, the system has a solid-state memory 941. The solid-state memory 941 is typically connected to the system bus 921 through a non-removable memory interface such as interface 940, and USB drive 951 is typically connected to the system bus 921 by a removable memory interface, such as interface 950.
A user may enter commands and information into the computing system 900 through input devices such as a keyboard, touchscreen, or software or hardware input buttons 962, a microphone 963, a pointing device and/or scrolling input component, such as a mouse, trackball or touch pad. These and other input devices are often connected to the processing unit 920 through a user input interface 960 that is coupled to the system bus 921, but can be connected by other interface and bus structures, such as a parallel port, game port, or a universal serial bus (USB). A display monitor 991 or other type of display screen device is also connected to the system bus 921 via an interface, such as a display interface 990. In addition to the monitor 991, computing devices may also include other peripheral output devices such as speakers 997, a vibrator 999, and other output devices, which may be connected through an output peripheral interface 995.
The computing system 900 can operate in a networked environment using logical connections to one or more remote computers/client devices, such as a remote computing system 980. The remote computing system 980 can a personal computer, a mobile computing device, a server, a router, a network PC, a peer device or other common network node, and typically includes many or all of the elements described above relative to the computing system 900. The logical connections can include a personal area network (PAN) 972 (e.g., Bluetooth®), a local area network (LAN) 971 (e.g., Wi-Fi), and a wide area network (WAN) 973 (e.g., cellular network), but may also include other networks such as a personal area network (e.g., Bluetooth®). Such networking environments are commonplace in offices, enterprise-wide computer networks, intranets and the Internet. A browser application may be resonant on the computing device and stored in the memory.
When used in a LAN networking environment, the computing system 900 is connected to the LAN 971 through a network interface 970, which can be, for example, a Bluetooth® or Wi-Fi adapter. When used in a WAN networking environment (e.g., Internet), the computing system 900 typically includes some means for establishing communications over the WAN 973. With respect to mobile telecommunication technologies, for example, a radio interface, which can be internal or external, can be connected to the system bus 921 via the network interface 970, or other appropriate mechanism. In a networked environment, other software depicted relative to the computing system 900, or portions thereof, may be stored in the remote memory storage device. By way of example, and not limitation, the system has remote application programs 985 as residing on remote computing device 980. It will be appreciated that the network connections shown are examples and other means of establishing a communications link between the computing devices that may be used.
As discussed, the computing system 900 can include mobile devices with a processing unit 920, a memory (e.g., ROM 931, RAM 932, etc.), a built-in battery to power the computing device, an AC power input to charge the battery, a display screen, a built-in Wi-Fi circuitry to wirelessly communicate with a remote computing device connected to network.
It should be noted that the present design can be carried out on a computing system such as that described with respect to shown herein. However, the present design can be carried out on a server, a computing device devoted to message handling, or on a distributed system in which different portions of the present design are carried out on different parts of the distributed computing system.
In some embodiments, software used to facilitate algorithms discussed herein can be embedded onto a non-transitory machine-readable medium. A machine-readable medium includes any mechanism that stores information in a form readable by a machine (e.g., a computer). For example, a non-transitory machine-readable medium can include read-only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; Digital Versatile Disc (DVD's), EPROMs, EEPROMs, FLASH memory, magnetic or optical cards, or any type of media suitable for storing electronic instructions.
Note, an application described herein includes but is not limited to software applications, mobile applications, and programs that are part of an operating system application. Some portions of this description are presented in terms of algorithms and symbolic representations of operations on data bits within a computer memory. These algorithmic descriptions and representations are the means used by those skilled in the data processing arts to most effectively convey the substance of their work to others skilled in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of steps leading to a desired result. The steps are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like. These algorithms can be written in a number of different software programming languages such as C, C++, HTTP, Java, Python, or other similar languages. Also, an algorithm can be implemented with lines of code in software, configured logic gates in software, or a combination of both. In an embodiment, the logic consists of electronic circuits that follow the rules of Boolean Logic, software that contain patterns of instructions, or any combination of both. Any portions of an algorithm implemented in software can be stored in an executable format in portion of a memory and is executed by one or more processors. In an embodiment, a module can be implemented with electronics hardware such as electronic circuits including transistors, software blocks of functionality such as an application, routine, algorithm, etc., and combinations of the software cooperating with an electronic circuit.
It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the above discussions, it is appreciated that throughout the description, discussions utilizing terms such as “processing” or “computing” or “calculating” or “determining” or “displaying” or the like, refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers, or other such information storage, transmission or display devices.
Many functions performed by electronic hardware components can be duplicated by software emulation. Thus, a software program written to accomplish those same functions can emulate the functionality of the hardware components in input-output circuitry. Thus, provided herein are one or more non-transitory machine-readable medium configured to store instructions and data that when executed by one or more processors on the computing device of the foregoing system, causes the computing device to perform the operations outlined as described herein.
References in the specification to “an embodiment,” “an example”, etc., indicate that the embodiment or example described may include a particular feature, structure, or characteristic, but every embodiment may not necessarily include the particular feature, structure, or characteristic. Such phrases can be not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is believed to be within the knowledge of one skilled in the art to affect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly indicated.
While the foregoing design and embodiments thereof have been provided in considerable detail, it is not the intention of the applicant(s) for the design and embodiments provided herein to be limiting. Additional adaptations and/or modifications are possible, and, in broader aspects, these adaptations and/or modifications are also encompassed. Accordingly, departures may be made from the foregoing design and embodiments without departing from the scope afforded by the following claims, which scope is only limited by the claims when appropriately construed.
